Defensive publication

ABSTRACT

DISCLOSED IS A PROCESS FOR PREPARING A FLAME RESISTANT, HEAT TRANSFER PRINTED FABRIC. ACCORDING TO THIS PROCESS A HEAT TRANSFER PRINTING PAPER IS PREPARED BY APPLYING A SUBLIMABLE DISPERSE DYE TO SELECTED LOCATIONS OF THE PAPER AND UNIFORMLY APPLYING TO THE PAPER A SUBLIMABLE ORGANIC BROMINE COMPOUND OF AT LEAST 6 CARBON ATOMS CONTAINING, BASED ON THE WEIGHT OF THE ORGANIC BROMINE COMPOUND, FROM ABOUT 40 TO ABOUT 85 WEIGHT PERCENT BROMINE. A POLYESTER FABRIC AND THE HEAT TRANSFER PRINTING PAPER ARE THEN BROUGHT IN JUXTAPOSITION AND THE FABRIC. ORGANIC BROMINE COMPOUND AND DISPERSE DYE ARE HEATED IN A TEMPERATURE RANGE OF ABOUT 200-215*C. IN A PREFERRED EMBODIMENT OF THIS PROCESS THE ORGANIC BROMINE COMPOUND IS A PHOSPHORUS-CONTAINING ALIPHATIC BROMINE COMPOUND. IN A STILL MORE PREFERRED EMBODIMENT OF THIS PROCESS THE ORGANIC BROMINE COMPOUND IS TRIS(2,3-DIBROMOPROPYL PHOSPHATE) AND THE FABRIC IS 100% POLY(ETHYLENE TEREPHTHALATE).

HEAT TRANSFER PRINTED FABRIC Gary L. Bond, 1352 Warpath Drive, Apt. 1, Kingsport, Tenn. 37664 Filed July 16, 1973, Ser. No. 379,874 Int. Cl. 341m 5/18 U.S. Cl. 117-362 No Drawing. 7 Pages Specification Disclosed is a process for preparing a flame resistant, heat transfer printed fabric. According to this process a heat transfer printing paper is prepared by applying a sublimable disperse dye to selected locations of the paper and uniformly applying to the paper a sublimable organic bromine compound of at least 6. carbon atoms containing, based on'thc weight of the organic bromine compound, from about 40 to about 85 weight percent bromine. A polyester fabric and the heat transfer printing paper are then brought into juxtaposition and the fabric, organic bromine compound and disperse dye are heated in a temperature range of about 200-215" C. In a preferred embodiment of this process the organic bromine compound is a phosphorus-containing aliphatic bromine compound. In a still more preferred embodiment of this process the organic bromine compound is tris(2,3-dibromopropyl phosphate) and the fabric is 100% poly(cthylcnc terephthalatc).
